To all whom it may concern: I I

Be it known that I, FRANK L. F unseen,

a citizen of the United States, residing at.

Graniteville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful mprovements 1n Sectional Conveyers for Drying Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to conveyors, and particularly to sectional conveyors such as are used in drying machines for conveying wool, cotton. hair, etc, and the general object of my invention is the provision of a conveyer comprising a' plurality of remova ble sections, so that should any part of any one or more sections become damaged, or incapable of performing its work, the damaged conveyer section. may be easily removed and a new'section inserted, thereby avoiding the expense of purchasing an entire new conveyer.

Still another purpose consists in the pro.

vision of improved means for use in con necting the sections of the conveyer to the chains, such that by simply forcing the chain laterally a section can be easily and very quickly removed, to permit the insertion of a new one.

A further object is to provide means whereby the sagging of the conveyer between the sprocket wheels thereof is prevented, and further to provide means for connecting the sections of the conveyer to the chains which will support the sections of the conveyer above the centers of the connecting means so that the outer faces of the sections may present practically a plain and unobstructed surface.

Other objects will appear in the course of the following description.

In the drawings Figure 1 is a view showing the applica tion ofthe improved sectional conveyer or apron to a drying machine;

Figure 2 is a cross sectional-view on line 22 of Figure 1;

Figure 3 is a plan view of a portion of the conveyer or apron;

Figure 4 is a longitudinal on line 4-4 of Figure 3;

Figure 5 is a horizontal sectional view through a portion of the apron or conveyer sectional view showing the tubes 12 and the pins 16, which engage the tubes;

Figure 6 is a sectional view of a modified form of connection between the apron or conveyer sections, showing the sections as extending from the upper portions of the tubular rods 12, so that the conveyer is flat or-even on its top face;

Figure 7 is a longitudinal sectional view of a modified form of sectional conveyer or apron as applied to a drying machine;

Figure 8 is an enlarged plan view of a portion of the conveyer or apron, wherein the conveyer sections are of the same length as the links of the chains, which carry the conveyer sections;

Figure 9 is an enlarged detail perspective view of the links shown in Figure 8, showing how the conveyer sections are fastened to the links, which are the same length as the conveyer sections; and

Flgure 10 is a sectional view of a modified form of connection between the apron or conveyer sections, wherein the holding pins are rectangular n cross section.

Referring to the drawings, 1 and 2 designate the opposed drums of a drying machine, over which the apron or conveyer travels. The shafts 3 of the drums carry sprocket wheels 4,with which the chains 5 ofthe sectional conveyer engage. lnterposed between the drums and adapted to support the upper and lower stretches of the chains are angle iron supports 6. The chains are made up of suitable links, such as flat strips 7, which are connected by the pins 8. The ends of the pins are headed as at 9, thereby retaining the links connected together in sequence. Suitable rollers 10 are mounted upon the pins 8, and engage with the angle iron supports.

The conveyer or apron proper is made up of a'plurality of perforated or wire fabric sections 11, the ends of which are connected to tubular rods 12. In order to connect the sections to the rods, sheet metal strips are bent upon themselves to form sleeves 13,

' through which the rods 12 extend. The end portions 14 of the sheet metal strips clamp the upper and lower faces of the foraminous sections, andare riveted thereto as at 15. .Obviously, as shown in Figure 5, the rod:

- inner ends of the pins are extended toward each other, and are adapted to detachably engage in the ends of the tubular rods, thereby supporting the conveyer or apron sections upon the chains. 3

Obviously the apron or conveyer sections can be easily detached, by simply raising the chains from engagement with the angle iron supports at a suitable point between the drums, and pulling the chain'laterally, causing'the pins to disengage from the tubular rods. 1 I

' In Figure 7 the drums 1 and 2 shown in Figures 1 and 2 are omitted, and in lieu thereof octagonal sprockets 20 are employed. These sprockets are engaged by the chains 21, which are made up of alternate long and short links 23 and 24. The lon links 23 are substantially equal to the fiat edges-22 of the sprockets. ounted between the links 23 upon headed pins 25 are rollers 26, which engage the transverse semi-circular recesses 27 of the faces 22 of the sprockets, thereby prer venting the chains from slipping relatively to the sprockets. As the chains travel from the angle iI'on supports 6 the rollers 26 are I in a position to engage thesemi-circular recesses 27 of the sprockets.

are arranged so that certain of said longitudinal edge portions will overlie the side faces of the sprockets, whereasthe links 24 may engage upon short fiat edges 28 formed between the edges 22 of the sprockets.

In Figures 7 8 and 9 the pins 29 (which correspond to the pins 16) have elongated reduced portions '30, which engage through the ends of the links 23 and the links 24, thereby connecting the links, and at the same time holding the pins to the, chains. The outer ends of the reduced portions 30 are headed at 31, so as to retain thedinks 23 and 24 in position and between the heads 31 and the shoulders 32. y

The inwardly projecting portions 33 of the pins loosely engage the ends of the tubular rods 34, to which the conveyer or apron sections 11 are connected .b means of the sheet metal strips, which are ent upon themselves to form cylindrical sleeves 35. The flanges of the sheet metal plates are riveted or otherwise secured to the perforated conveyer or apron sections as at 36. Obviously the conveyer or apron shown in Figures 7 The links 23 and 8 function the same as the conveyer or apron shown in Figures 1 and 3, the only exception being that the construction is slightly modified, to the extent that the apron or conveyer sections are substantially equal in length to the links 23, so that when the chains pass about the octagonal sprockets, the apron or conveyer sections will conform to the contour of the sprockets. When the chains shown in Figures 7 and 8 pass about the sprockets, the rollers 26 may engage the semi-circular cavities of recesses 27, so that the chains will properly operate. vious that though the .drum is omitted in Figures 7 and 8, it may be included in this construction, if so desired, it being obvious that the drum would then conform to the shape .of the sprockets.

- In Figure 10,1 illustrate a modified construction in which the tubular rods 12' are rectangular in cross section and the sheet -metal sleeves 14' have those portions which engage the margin of the wire "mesh 11 disposed tangentially to the axial center of the tubular rods 12 and practically flush with the upper surface of said rods so that thus the wire mesh is supported above the centers of these rods and the conveyer apron has practically a plain surface from one drum to another. In Figure 6, I show a like construction to that in Figure 10, but in this case the rods 12 are cylindrical in form, the sleeves 13 are also cylindrical in form to embrace said rods, and the margins of the sleeves, as, at 14, extend tangentially with respect to the axes of the rods 12*.
